Application led September 8, 1926. Serial No. 134,271.

-My invention relates to improvements in metal windows. One of its objects is to provide an improved metal window frame and sash structure. Another object is to provide a window frame and sash structure adapted to be built up from extruded metal forms or bars by cutting and mitering the same.

`Another object is to provide improved means to iirmly and rigidly connect the frame and sash sections together, at their mitered joints. Another object is to provide improved extruded metal bars especially adapted to the construction of Window frames and sashes. Another object is to provide improved means to exclude wind and water. Another object is to provide improved means to detachably secure the glazed panel or panels in place relative to sash frame. My invention also comprises certain details of form and arrangement and combination of components, all of which will be fully set forth in the description of the accompanyingdrawings in which Fig. 1 is a plan of a window frame and sash embodying my improvements.

Fig. 8- is a view similar to Fig. 7 illuslrating a modification thereof.

Fig. 9- a section through the window frame similar to that shown in Fig. 3,' and illustrating a modification thereof.

The accompanying drawings illustrate the preferred embodiments of my invention in Figs. l to 7 of which 15 represents the window frame and 16 the window sash, which may be either of the easement type in which the sash is attached to the frame by means of hinges 17 and opens inwardly or of the slidone of the miter joints of Fig. 3 through one of the miter joints ing type in which one or more sash members are arranged to slide vertically in ways or guides on the frame. In the drawings I have illustrated the Casement type of Aframe and sash.

One of the prime objects of myinvention is to provide forms or structural bars from which the top, bottom and sides of the frame and sash may be formed by cutting and mitering sections of said structural bars to form the rectangular frame and sash mem-- bers' and which structural bars lend themselves to and facilitate tirmlyuniting 'their ends together at their mite'red joints and staying and rendering said joints and completed frames and sashes firm, rigid, permanent and reliable, and which also facilitate accuracy formity of said structural bars.

The structural bars substantially as shown of the desired crosssection having finished plane faces, plane faces parallel to each other, and plane faces meeting at` right angles are adapted to be produced inquantity and with accuracy of dimensions and finished surfaces by a process of extrusion, whereby the metal is forced under heavy pressure through dies. The structural bars from which the window frames are formed are preferably of a general H or I-beam type, to provide a maximum of strength and resistance to' transverse strain. On the outer side of the cross bar 20 of the I-beam, the free arms 21 and 22 are provided with inwardly directed ribs 24 and 25 formed integral with and extending lengthwise, leaving intervening recesses 26 and 27. At the opposite side of the cross"bar 20 the free arm 28 is shorter than the free arm 29, thereby providing for the 'sash to make two independent face to face contacts with the frame one with the side of arm 28 and the other with the side of 'arm 29, and together tending to doubly exclude wind and weather. The arms 28 and 29 are preferably provided with inwardly turned ribs 30 and 31 providing recesses 32 and 33 intermediate of the cross bar 20 and the ribs 30 and 31, which receive and hold in place the opposite edges of a weather strip or strip of resilient sheet metal 34, which is curved transversely of its length and sprung into place, and which also bears yieldingly upon a rib or fulcrum extending inwardly from the cross bar 20. The strips 34 are readily detachable and replaceable.

and quantity production and uni- When I portion of the weatherstrip 34 is yieldingly engaged 4by a rib'or arm 36 extending outward y from the sash, and which further serves to exclude wind and moisture.

The structural bars from which the sash frames are constructed are provided with plane faced arms 40 and 41 which close against corresponding plane faced members 28 and 29 upon the window frame. The sash bars are also provided with a plurality of inwardly directed ribs, for instance 42, 43, 44, and 45, with spaces 46, 47, 48, and 49 intervening between said ribs and the cross bar 50 of the sash bar. Upon the opposite side of the cross bar 50 Jfrom the arms 40 and 41 is a projection 51r outside of the window pane 52, and preferably a relatively smaller rib 53 inside ofthe window pane.

In order to render these structural forms available and practical for the construction of window frames and sash frames, it is important to be able to secure themeeting ends of the structural bars where they are mitered together, with accuracy, and with a more than usual degree of firmness and rigidity, in order that the frames may be 4accurate in the rst place, and retain their accuracy through long periods of use under the strains to which. window frames and Isashes are normally subjected and so that the plane meeting faces of all the members of the window frames and sash frames may meet 'to exclude the weather and may continue to do so. To accomplish this purpose I provide angle plates 55 substantially as shown in Fig. 5 which are ofsuiicient width to occupy practically all of the space between the side arms or walls 21 and 22 of the window frame, see Fig. 3 and of sutiicient thickness tot tightly into and occupy practically all of the spaces intermediate of the cross bar, 20 and the inwardly directed ribs 24 and 25, see Fig. 7. These angle plates 55 may be introduced endwise into the recesses in the meeting ends of the adjacent structural bars or frame sections as the window frames are assembled. After the frames have been assembled, I preferably secure the angle plates 55 in place by two ormore countersunk screws 56, and if desired the angle plates 55 may then be sweated, brazed or soldered in position without material injury to the surface of the window frame.

The sash frames, see Fig. 6, are united in a similar manner employing two angle plates 58 and 59, similar to the angle plate 55, but of less width. .The plate enters and lits tihtly into the space' between the arm 41 an the arm 36 and also fits tight-ly into the spaces between the cross bar 50 and the inwardly directed ribs 42 and 43. The angle plate 59 tits tightliyobetween the arm 36 and the arm 40 and a tightly into the spaces am sah is closed the intermediate .plate 66 near one edge,

intermediate of the cross bar 50 and the inwardly directed ribs 44 and 45. The angle plates 58 and 59 may be secured by screws or by, brazing or soldering, or both substantially as described for securing the angle plates 55 in place.

As a further means of increasing the rigidity of the sash frames, I have shown in Fig. 6 an angle plate 60 of the general type shown in Fig. 4 attached in place outside of the inwardly directed ribs 42 or 45 or both of them. Where the arm 36 is omitted, only one angle plate is employed in place of the two angle plates 58 and 59 to lock the corners of the window sash frames.

In the modification shown in Fig. 8 which is adapted to the construction of large and heavy window frames and sashes, I have shown structural bars having a cross bar 63 corresponding to the cross bar 2O or 50 of Fig. 3, and an inwardly directed rib 64 having an overhanging ledge 65, and spaced a relatively greater distance from the cross bar 63. An angle plate 66 of the general type shown in Fig. 5 is employed jointly with one or,with two angle plates 67 of the general type shown in Fig. 4 so arranged that the inner edge of the angle plate 67 is in contact with the outer face of the angle or if two plates 67 are employed engaging near both edges of plate 66. The outer edge of the angle plate 67 is locked into the channel 68 formed by the rib 64 and its led e 65. Both the angle plate 66 and the ange late 67 are held in place by screws 69 an may be brazed or soldered into place if desired.

In the modification Fig. 9, I have shown two angle plates 70 and 71 of the general type shown in Fig. 4 which are interposed between a cross bar 73 at one edge and an inwardly directed rib 74 at the other edge, and held in place by screws 75, and which are also adapted to be brazed or soldered in place.

The structural hars are adapted to he produced from bronze or similar metal or alloy adapted to resist corrosion for long periods of time, and to be produced with accuracy,

and in quantity.

In order to lsecure the pane or panes of glass in place, I have preferably provided a relatively soft and flexible member 77 of rubber or felt which is interposed between .the metal of the sash frame and the edge of the pane, and a channel shaped strip of resilient sheet metal 78 one edge of which is placed between the edge of the pane and the sash fra-me while the opposite edge of said strip is engaged beneath the edge of the rib 53 to yieldingly and detachably hold the pane of glass in place relative to the sash frame, there being a strip 78 along earch side of the pane.
